Right Colonic Giant Angiodysplasia With Intraluminal And Retroperitoneal Hemorrhage: Case Report And Literature Review

Angiodysplasia is the most frequent vascular abnormality on the gastrointestinal tract. It is an abnormal accumulation of dilated vessels with a thin and fragile wall that can easily break. Normally found in the right colon and measures between 2 and 5 mm. We describe a case of a 72 year old woman with a giant right colonic angiodysplasia of 3.5 cm of width with intraluminal and retroperitoneal hemorrhage. The patient had a history of consumption of antiplatelet drugs due to a prior myocardial infarction and three episodes of hematochezia. The colonoscopy showed ulcerated cecum hemangioma, active bleeding and management with hemospray. The treatment of the angiodysplasia was a right hemicolectomy and a laparoscopic mechanical ileotransverse anastomosis.
